DRAFT-GEAR YGKE.

Specification of Letters Patent.

Patented Oct. 9, 1917.

0rig'inal application led September 13, 1912, Serial N o. 720,153. Divided and this application led September 8, 1914, Serial No. 860,583. Renewed August 27, 1917.

To all 'whom it may concern."

Be it known that I, Suor B. HAsEL'rlN n, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois have invented a certain new und useful lmprovement in Draft-Gear Yokes, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in draft gear yokes.

The object of my invention is to provide a simple and efficient means of connecting the draw-bar and draft yoke in railway draft rigging, and one in which the draw-bar and draft yoke may be easily connected and disconnected.

In the accompanying drawings formin a part of this specification, Figure l is a side elevation of the forward end of a draft yoke and the rear end of a draw-bar embodying my invention; Fig. 2 is a view partly in plan and artly in horizontal section on line 2-2 of 1g. l; Fig. 3 is a vertical sectional View on line 3-3 of Fig. 2; Fig. 4 is a transverse sectional view on line 4-4 of Fig. l; and Fig. 5 is a detail Aerspective view of the block employed wit my improvement.

`In said drawing, the draw-bar shank 32 and the` butt thereof 33 are shown as provided with the usual u per and lower transverse shoulders 34 and) 35 respectively; the draft yoke 36, the forward end of which is shown in the drawing, has a'n upper strap 37 and a lower strap 38; the upper strap 37 being provided with a downwardly turned gib 3engagin the upper shoulder 34 of the draw-bar. lle lower strap 38 is vided with the downward turn or ben 39, in front of which it is forwardly extended in a plane parallel with the o posite portion of the upper strap and a su cient distance therefrom to permit the butt of the drawbar to clear the gib 38 in inserting the drawbar through the forward opening of the yoke. The upper and lower straps of the yoke are forwardly joined by the lateral Webs or plates 40, 40, thus providing a head for the yoke with a box-like opening 41, into which the drawbar is received. The webs 40, 40, are transversely provided near their lower edges with the slot 42 to receive the transverse key 43, which passes therethrough Serial N0. 188,483.

and through the transverse perforation 44 in the L-shaped block 45. The block 45 has an upright member 46 and a flat member 47, forminr the shoulder 48, against which the lower sioulder 35 of the butt of the drawbar engages in normal position with the draft rigging. The top face 49 of the member 47 of the block 45, when in position, is substantially even with the inner portion or upper face 50 of the lower yoke strap 38, back oi' the bend 39 therein. The key 43 is provided with the perforations 51, 51 at its ends to receive the cotters or pins 52, 52.

The operation of my device will be clear. To remove the drawbar, the block is withdrawn, permitting the butt of the draw-bar to be moved downwardl so that the upper shoulder thereof may c ear the gib of the upper yoke strap and be forwardly withdrawn. To connect the draw-bar with the yoke, the butt of the draw-bar is mserted in the box-like opening of the member of the yoke, lifted to osition so that the upper shoulder of the raw-bar engages the gib in the upper strap of the yoke and then the block is inserted in the lower' ortion of the said opening so that the shoul er thereon en gages the lower shoulder of the drawb'ar and the block is then secured in position by passing the key therethrough. It will be seen that on the rearward movement of the draw-bar, the butt of the same will engage 4 directly with the followers or compression resisting members within the yoke and without strain upon the yoke, while on the forward movement of the draw-bar the shoulders of the same will be in engagement with the shoulders provided on the upper strap of the yoke and upon the block. p

This application is a division of my copending application No. 720,153, filed September 13, 1912, for improvement in means of connectin drawbar to draft yoke in railway draft rigging.

I claim l. In a device of the class described, 'a draw-bar provided with oppositely disposed shoulders, a yoke forwardly provided with a'laterally slotted, hollow box-like head to receive the draw-bar, a,transverse shoulder within said yoke adapted to engage one shoulder of the draw-bar, a removable block provided with a shoulder adapted to engage the other shoulder of said draw-bar and a key adapted to secure said removable block within the said head.

2. The combination, with a yoke having top and bottom members, the top member having a coupler engagin gib, and apertured side plates uniting t e forward ends of the top and bottom members, of an apertured locking block adapted to lt between the side plates and having a coupler engaging gib, and a key for passing through the apertures of the side plates and the locking block.

3. A coupler yoke comprised of two forwardly extending arms adapted to receive between them a coupler liner block, a filler block located between the coupler liner block and the lower yoke arm, said filler block having a recess in its lower side adapted for reception of a key for securing the filler block to the yoke.

4. A yoke having longitudinally extending arms connected by side walls at their forward ends to form afhousing, opposite abntments within said housing, one of said abutments being formed on a longitudinally removable member, and a laterally removable key, for securing said removable member within the housing.

5. A coupler yoke comprised of longitudinally extending arms connected together at their forward ends to form a housing, a coupler butt inserted in said housing and having a pulling engagement with a wall thereof, a longitudinally removable filler Uoples of this patent may be obtained for ve cents each, by addressing the block seated on the opposite wall and'having a pulling engagement with the coupler bult, and securing means for said filler block removable laterally and in a plane en- 1tirely below the under side of said coupler utt.

6. As an article of manufacture, a yoke for draft riggings, said yoke having a hollow box-like head at the forward e thereof within which is adapted to be received a draw bar butt, the upper wall of said head being provided with a shoulder adapted for engagement with the upper shoulder of a draw bar butt under draft, the distance between the lower wall of said head and said shoulder on the upper wall thereof being sufficient to permit the insertion of the draw bar butt by longitudinal movement relatively to the yoke, a shouldered locking block arranged to extend under the lower surface of the draw bar butt and to engage the front face of the lower shoulder thereof, said block, when in position, supporting the draw bar butt with the upper shoulder thereof in alinement with the shoulder of said head, and a removable key extending through slots provided in the yoke head and in said block for Iretaining the latter in operative position.
